Description:
The Permaculture Research Institute (PRI) describes permaculture as "the harmonious integration of landscape and people providing their food, energy, shelter, and other material and non-material needs in a sustainable way. It is also the conscious design and maintenance of agriculturally productive ecosystems which have the diversity, stability and resilience of natural ecosystems." In addition to this definition of permaculture, the PRI website contains a collection of related articles, a Discussion Forum, an annotated Photo Gallery, and brief descriptions of several recommended books.
